 On 16 January 1919, Prohibition was established with the ratification of the Eighteenth Amendment to the United States Constitution prohibiting the "...manufacture, sale, or transportation of intoxicating liquors within, the importation thereof into, or the exportation thereof from the United States..." and Congress subsequently passed the Volstead Act to enforce the law.New Jersey, coincidentally, was the 46th and last state to ratify the Eighteenth Amendment—not doing so until 9 March 1922.Although it was largely unsuccessful, Prohibition would last for 14 years, becoming increasingly unpopular during the Roaring Twenties and the Great Depression.
